4367-3. Do-it-yourself maintenance
IS300h_EE(OM53B95E)
CAUTION
The engine compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or seri-
ous injury, observe the following precautions.
When working on the engine compartment
Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-infor-
mation display and the “READY” indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine drive
belt.
Be careful not to touch the engine, power control unit, radiator, exhaust mani-
fold, etc. right after driving as they may be hot. Oil and other fluids may also
be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are
flammable.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the affected
area with clean water immediately.
If you still experience discomfort, consult a doctor.
When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is
high. (P. 446)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear
or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
